Abstract
The study was conducted on 12 animals divided into two equal groups to estimate the dynamic lung compliance in two groups of animals with or without diaphragmatic defect undergoing surgical interventions under isoflurane anaesthesia. In group I, transabdominal diaphragmatic herniorrhaphy was performed and in group II, right flank laparotomy was performed. Mechanical ventilation was initiated with the settings of 10 breaths/min, inspiratory time of 2 s, I:E ratio of 1:2. The peak inspiratory pressure (PIP) of 10 and 20 cmH2O was maintained during surgery in group I and group II animals, respectively. The dynamic lung compliance was significantly (P<0.01) higher in group I animals than in group II. The mechanical ventilation with peak inspiratory pressure setting of 10 cmH2O in group I animals during transabdominal herniorrhaphy maintained the cardiopulmonary parameters within the physiological limit and did not produce any deleterious effect on the lungs.
